By using the Multi-Size Technique to turn themselves into a human-sized ball, the user tucks in their limbs and uses chakra to propel themselves into a powerful roll. Due to the force of the rotation, it will cause those that come into contact with it to be pulverised. However, a drawback of this technique is that it is difficult for the user to turn in this form. This technique also has the added effect of plugging up the user's ears.
